MEMS Ultra-Low Power Oscillator, 32.768 kHz Quartz XTAL Replacement
Example 1: Full‐swing LVCMOS
• Vdd = 1.8V
• Idd Core = 900nA
• Load Capacitance = 10pF
• Idd Output Driver: (65nA/V)(1.8V) = 117nA
• Load Current: (10pF)(1.8V)(32.768kHz) = 590nA
• Total Current = 900nA+117nA+590nA = 1.6µA
Example 2: NanoDrive™ Reduced Swing
• Vdd = 1.8V
• Idd Core = 900nA
• Load Capacitance = 10pF
• Vout_pp (Programmable): V_OH – V_OL = 1.1V - 0.6V = 500mV
• Idd Output Driver: (65nA/V)(0.5V) = 33nA
• Load Current: (10pF)(0.5V)(32.768kHz) = 164nA
• Total Current = 900nA + 33nA + 164nA = 1.1µA
